        <ul>
            <li>用invert和hue-rotate两个 CSS3 过滤器来实现</li>
            <li>filter: invert() — 是从0到1的刻度，1是从白变黑。</li>
            <li>filter: hue-rotate() — 用于改变你元素的颜色，同时或多或少保持原本相同的色系。这个属性的值可以从0deg到360deg。</li>
            <li>这里我们会发现图片的颜色会受影响，并不是很美观，使用 css 过滤器是无法完美切换黑暗模式的。</li>
            <li>不过使用 JavaScript 辅助就可以完美的切换黑暗模式。</li>
